The human heart is a funny old thing. One minute it can be tough as ol' boots and locked up tight like a rusty sea chest with a broken lock, the next minute it's owned by some furry or feathered creature who ought not to mean much but ends up meaning the world.
I learned this the hard way recently when my rascal of a kat went missing (I spell it that way because he's not quite kitten, but also not quite cat, and going through that rangy, awkward teenage stage with all the mischief that goes with it).
Dave is an SPCA rescue cat, a surprise Christmas present from a year ago, and through a winning combination of nurture and nature, his personality and bearing is part human, part dog and 100 per cent part of our family.
Dave loves our dog, Greta, like a little brother should. They sleep together, play rough together and even huddle on the porch in the cold, driving rain together (despite Dave having a cat door and a bed by the fire).
The first thing we hear after the alarm goes off each morning is Dave galloping down the wooden floors of the hallway, before he flies at us with noisy demands for the first snuggle of the morning before Greta (not a morning dog) eventually comes for one too.
